How did the Romans use innovation in building the Pantheon to create the world's largest unsupported dome?
The used heavier ballast stone to lighten the concrete at the top of the dome.
They used pumice stone to make their concrete lighter at the top of the dome.
O They used knuckle sized rocks to lighten their concrete at the top of the dome.

name the above painting and its artist. how has the artist used balance, variety, and movement in this piece to emphasize the man waving the cloth, in the upper right-hand corner? be specific in your response.

i believe the answer is  the similarity is that both are sacrifices which have the same purpose and sacrifice - jesus christ, but the difference is in offering of that sacrifice.

the similarity is that both are sacrifices which have the same purpose (repenting our sins) and sacrifice - jesus christ.  the difference is in the way of the offering that sacrifice. the sacrifice of jesus on the calvary is sacrifice of his actual living body and blood, but the sacrifice of the mass is the sacrifice of the jesus through bread (body) and blood (wine). in the sacrifice on calvary jesus was offered for us; while at mass he offers himself through us.
